Portuguese Nasal Vowels

If we elevate the velum only to allow some air to pass through the nose AND the mouth, an extra resonation occurs in our nasal cavities, and we have what we perceive as a "nasal vowel". We already do all these things without ever thinking about it.

Nasal-Oral Vowel Pairs

Just as the rounded vowels have unrounded counterparts, the nasal vowels have oral counterparts. They are listed below. Note that for simplicity sake, I am including both Brazilian and European Nasal Vowels.

If you make the unrounded vowel sound /i/ and round your lips WITHOUT changing ANYTHING else in your speech organ, you will get the rounded counterpart.

Similarly, if you make the oral vowel /o/ and lower your velum to allow some air to pass through your nasal passage WITHOUT changing anything else in your speech organ, you will get the nasal counterpart - /õ/.

In the audio files below, I show this by alternating between the different nasal vowels and their oral counterparts. Listen and try to tune your ear to the difference. You can try to mimic the sounds yourself, but do not worry if you can't get them perfect. We will focus more on articulation later.

Because nasal vowels occur rarely in English, our ears are not sensitive to different types of nasal vowel sounds. Our brains mush them all together with the "mmm" sound.

Do not get frustrated if these sound differences are not 100% obvious to you yet. Motor and perception skills take time and practice to develop.

You should return to this page as often as you gain more practical experience with Portuguese sounds.
